The Sox are 11-17 in 1-run games, and of all the teams struggling to score are the only ones showing above average on-base skills. There has been a lot of bad luck here. That and corner outfielders turning into pumpkins (or injury cases). The Sox' health has not been as favorable as it was last year.
That being said, the run prevention has been pretty good. Peavy has struggled, but if he is the worst starter - that's not bad. The top 2 is as good as any in the league, and the depth might be better than that. There is a run to be had in this team - has been frustrating to not be able to get to it.
